One analogue of this law relates the expectation value of an operator to its commutator with the Hamiltonian; that analogue, Ehrenfest's theorem, reduces to this equation in the limit of large quantum numbers. A term accounting for the loss of exhaust is added to one side of this equation to obtain the ideal rocket equation. The impulse-momentum theorem follows from this law, whose rotational analogue states that torque equals moment of inertia times alpha. Its original form stated that net force equals the time derivat

A term accounting for the loss of exhaust is added to one side of this equation to obtain the ideal rocket equation. The impulse-momentum theorem follows from this law, whose rotational analogue states that torque equals moment of inertia times alpha. Its original form stated that net force equals the time derivative of momentum. For 10 points, name this law of physics which states that force equals mass times acceleration.
